4 Claims. 1

This invention relates to drain devices for insertion in outlets of basins, sinks and the like, and more particularly to a combination valve and strainer adapted to be removably associated with a drain outlet.

It is primarily within the contemplation of this invention to provide a valve and strainer construction which will be conveniently adaptable for use in the basins of beauty parlors and barber shops where it is necessary not only to readily control the flow of water into the outlet, but also quickly and easily to remove the entire unit for cleaning and repair purposes.

It is also an important object of my invention to enable the unit to be readily and firmly attached to the outlet fixture, whereby it will remain in place and securely held againstA dislodgement.

It is a further object of my invention to enable the unit to be readily disconnected from the outlet fixture by a simple manipulation. And in this aspect of my invention it is another object to effect such disconnection without the employment of any special outwardly disposed disconnecting members which might interfere with the operator or cause injuryto the operator or customer. In a preferred construction of my invention, this object is accomplished by providing the valve member with means for detachably holding the unit 3 in place.

Another object of this invention is to provide means for enabling the unit to be readily assembled as well as disassembled for cleaning purposes or repair.

And it is within the further contemplation of my invention to enable the above-mentioned objectives to be attained by a simple, readily fabricated and inexpensive device.

Other objects, features and advantages will appear from the drawings and the description hereinafter given.

Referring to the drawings,

Figure 1 is a vertical diametral section showing a preferred embodiment of my invention operatively connected to an outlet fixture, the valve member being shown in its raised, intermediate non-obstructing position while holding the unit locked in place.

Figure 2 is a plan view of Figure 1.

Figure 3 is a fragmentary section of Figure l taken substantially along line 3 3.

Figure 4 is a fragmentary sectional View substantially like Figure 1, but showing the valve member in its upper position out of engagement with the locking mechanism.

Figure 5 isa fragmentary sectional View substantially like Figure 1, but showing the valve member in its lowermost or closed position,

Figure 6 is an enlarged fragmentary section of the arrangement of Figure 4, when the unit is out of its locked position.

Figure '7 is a bottom perspective view of the locking disc member employed in the above-referred to figures.

Figure 8 is a Vertical diametral section of a modified form of my invention, the valve member being shown in its lowermost position while holding the unit locked in place.

Figure 9 is an enlarged fragmentary section, like that of Figure 8, but showing the valve member in its raised or open position, and

Figure 10 is a bottom perspective view of th locking disc member employed in the structure of Figures 8 and 9.

In the form of my invention illustrated in Figures 1 to '7, the construction includes two coacting shells I5 and I6 movably connected so that shell I6 serving as a cap could, by manual manipulation, move longitudinally with respect to shell I5, the main casing. Although this connection could, within the contemplation of my invention, be effected in various known ways, such as by a telescopic sliding arrangement or bayonet structure, the preferred method, as illustrated, is a 0 threaded connection. More specifically, the said shells are provided with threaded portions I'I and I8, shell I6 being in overlapping threaded engagement with shell I5.

Shell I5 consists of two portions I9 and 29, the latter or lower portion being of reduced proportions, thereby providing the recessed circumferential shoulder 2|. The said lower portion 2U is adapted to be inserted within the outlet opening 22 of the basin or sink oor 23, the shoulder 2l being adapted to rest upon the surface 24 of the basin. The lower part of portion I9 of shell I5 is provided with a plurality of circumferentially disposed outlet apertures 25, the upper part of said portion I9 being adapted to accommodate the valve member 2B when in its upper position, such as is illustrated in Figure 1. The said valve member is adapted to slidably move vertically within portion I9 of shell I5, whereby it can when in its lower position entirely obstruct the apertures 25.

The valve member 26 has rotatably connected thereto the finger ring 21, the illustrated construction being a swivel arrangement comprising an eye member 28 (through which the ring extends) with anexpanded base 29 rotatably disposed within the recessed element 30 moulded or otherwise secured within the body of valve 26. The top wall 3| of the cap i6 is preferably of concave form and contains a diametrically disposed slot 32 of a length and width sufficient to allow the ring to enter therein or pass therethrough.

Disposed upon the circumferential inner seat 33 formed by the said shoulder portion 2l is the locking disc 34 preferably of resilient',l material; and punched out downwardly from the body of the disc are the two yieldably supported legs orY locking members 35 containing the outwardlyprotruding elements or ngers 36. Inthein'nor-- mal unstrained condition, each of these iingers is disposed within an opening 37(Figure=--6 'ofi the lower portion 2i] of the shell=|5, the position; of said openings being substantially at the level of the recess 38 within the wall of the outletfV portion 22. Such a recess is generally found in outlet Yfixtures cithisclass,4 .to-accommodate? the conventional; strainer,r disc,` which i ist, dispensed: with whengusingmysinventionz,

Byvreferringf to'. Figure 6:. it# will: be: obseryed thati the; depending: member- 35i extendsin its; said normal state, downwardly; and; inwardly-V withina the lower: portion: 20:; of shell"l 15;. The length ofifthe elementS' is preferably'suchptliat^ when member 35 is in its normal.retractedpiosieu tion', itl does'. not extend.' beyond the outerf surface off wall .20; the terminal of element; being: within .thea apertured; portionxS; ll'he .preferred proportions are such thatwhenthezlockingmemeber 3521's in .a verticalV position; oris pressed-flush againstz theinner. surface-of: wallZll; tlie elementi 36 will extendbeyondwall 2U-rand into-thefrecessi 381v to -hold the entirev unit against upward displacementf andI operatively lockediniplace. Itcis; however, also within the contemplation:ofthis invention, to nemploy it within outletixtures :not provided'withia recess :like 38; inlwhichevent the element 3S' willnierely` engage the adjacentasur facer oifoutlet w-all 221 andinithis-:manner fric-- tionally holdtthe unit againstdisplacement.

Extendingdownwardly-from .the valvefmemberf 261'- are two preferably. slightlyd resilient bars. 012l rods-:39150 spaced-and `proportioned tliatfthey are adapted toengage the lockinglegs 35and4 force` them outwardly into 7locking positions,y as-Yshown in Eiguresl and; The-length'offthese bars-is: such that they.I are operatively-'engageaibl'e wit-h1 the legs^35l not: only. when the-valve 26 isdn' its: lowermost closed position, at whichpositiontheoutlet' apertures are entirelylobstructed;l buti also when-it1 isin the intermediate'- upperopen posi tion` illustrated in Figure 11. It-willzbeobserved;V thatin either of 'these=positions; the bars-1392er tendthroughthe apertures dil; and being flanked'` by the-lateral walls 4i -of-saidapertures, the bars are prevented from movinglaterally',- and! the'- entireV valveM member 2B acccrdingly-- prevented fromrotating;

It'thusappears that-theY locking disci34 not-only` provides the locking membersr35 andan'anchoreage therefor',` but al'soserves as a guide forthe' bars 39"and as ameans toprevent a-rotation ofi the valve- 26; It isalsoiapparent that the-entire'- locking-disc 34canA readily be -assembled`in-place' by merely placing it upon the' circumferentialseat 33 (when the cap Iiv is removed from' shell' I5) and rotating it until" the-fingers.A1 35's1ap into theholesST;

Should-it bedesiredton disengagethe' entire` unit fromthe basin, the' cap I6` isfpartiallygun screwed; thereby raising the level yof top Wall 31 and accordingly permitting the valve 26 to be raised to its disengaging position, as illustrated in Figure 4. This is accomplished by simply grasping ring 21, and applying an upward pull, whereby the bars 39 are brought to a level above the disc 34 and out of engagement with the locking members 3'5. Said locking members, because of the resilient construction, will then return to their normal positions, as indicated in Figures 4 and 6, whereupon* the entire unit canwbe; withdrawn.

It is thus apparent that the valve member 26 can occupy three critical positions-the lowermost closed position where it obstructs the holes ZEzandimaintains the members 35 in their locking positions (Figure 5), the intermediate open position Wlierethe holes 25 are unobstructed but tlie'fmembers.zlifareY still in their locking positions (Figure 1), and the uppermost open position whereLth'e members 35 are disengaged from the outlet fixtures and the entire unit is in a condition to abeeremovedi (Figure 4) Theevalveifis rmly-zfmaintainedazinzits inter;l mediate'spositionibyfturmng the ring :2;so; thatfitrV rests; uporn tile-,uppersY wall13) whereby` thegvalve'; cannot be displaced downwardly.
